Scientific Description
The main goal of the TanDEM-X mission is the generation of world-wide, consistent, timely, high-precision Digital Elevation Models (DEM, <12 m posting and <2 m height accuracy) as the basis for a wide range of scientific research, as well as for operational DEM production.The TanDEM-X mission is a novel way to realize an operational single pass SAR interferometer utilizing TerraSAR-X technology in a new system context.

TanDEM-X satellites
TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) opens a new era in spaceborne radar remote sensing. The first bistatic SAR mission, is formed by adding a second, almost identical spacecraft, to TerraSAR-X and flying the two satellites in a closely controlled formation with typical distances between 250 and 500 m. Primary mission objective is the generation of a consistent global digital elevation model with an unprecedented accuracy according to the HRTI-3 specifications. Beyond that, TanDEM-X provides a highly reconfigurable platform for the demonstration of new SAR techniques and applications.
